Default 15+ Who's running a custom box-

Anyone running an 8" under the seat of a Super Crew 15+ in a custom box? Looking for ideas on what to do to fit an 8" under the rear seat. Not sure if I can forward fire it or if I'll have to down fire it. Have an Infinity Kappa 8" SSI and a 5 Channel Reference amp that I wanna toss in.

I'd say it looks like the mounting depth with that sub only allows for a front facing speaker.

if going with forward firing i would flush mount the sub. looks cleaner and easier to put a grille over it.

Check out MTI acoustics for some design ideas... they build them right. Look in their gallery, they also have a facebook page.

That is a pretty deep 8 inch subwoofer (5 3/4), plus it has a rear vent that needs at least an inch of space behind it. It will take more space to down fire it than forward with the clearance needed behind it and in front of it to the floor (1.5 inches).1.5 + 5.75 + 1 + 0.75MDF = 9 inches if downfiring.

Thanks for the replies guys. This is what I had in mind.

Didnít want it to go across the entire back floor but it might have to, not sure. The amp will be recessed in.

Also, still trying to figure out how high I can go. Doesnít seem like I have more than 8.5-9Ē up front. I also donít wanna ditch my all weather floor mats.

My skills unfortunately wonít be as good as MTI solutions. But they make some sick setups! They seem to make a lot of downfire solutions.

since you sub is going to stick out a bit why not cut another piece of 1/2" for the face. your sub will be recessed, won't change the airspace and it will look cleaner

I could definitely do that. Still not sure how Iím going to finish the box. Just trying to figure out basic design of the box.

I just built one. Holds a 10" image dynamics but I designed it to hold a 12". The ID speaker is 5 7/8" deep - you can see where I have a bumpout. The box is1.3 cu ft - 1.1 cu ft after accounting for port and speaker. The pictures are after primer coat of paint. It is down firing and tuned to 33hz.
